A)Patent
Patent fingerprints, on the other hand, can be made by blood, grease, ink, or dirt.
The substance would you expect to heat up faster is Substance A, which has a specific heat capacity of 0.452 J/g℃.
<h3>What is specific heat capacity?</h3>
The specific heat capacity is the amount of heat necessary to elevate 1 degree 1 kg of the substance. Its unity is J/gºC. We can calculate the heat that changes the temperature of a substance by the equation:
Q = mcΔT
Where Q is the heat, m is the mass, c is the specific heat capacity, and ΔT is the change in the temperature.
Thus, Substance A, has a specific heat capacity of 0.452 J/g℃.

Answer: e. demonstrate that the scientists conducting the trial are not biased in concluding that the drug is effective.
Explanation:
The clinical trials are performed in laboratories to determine the effect of drugs or medicines over the animal, plant or human subjects. This is necessary for validating the sale of medicines and drugs on the commercial scale.
The drug companies hire the independent research laboratories to conduct the clinical trials and provide unbiased results. The scientists of the independent laboratories will conduct research which will be fair and free from any kind of biasness to conclude the effectiveness of the drug. Hence, the results can be consider reliable.
